Abstract: Reconstruction of El Nino/Southern Oscillation (ENSO) activities over five centuries is now possible, based on the proxy Chinese climatic indicators of historical data from the periods between 1470 to 1990. This reconstruction provide insight into the temporal behaviour of El Nino and La Nina events during the last 520 years. The reconstructed time series of El Nino and La Nina activities have revealed the periodicity of a 10.38 years cycle (from 10.18 to 10.6) with a significance level of 99.9%. For this reason it might be questioned to what extend the Pacific climate system is controlled by the sun activity; its periodicity varies between 10 to 12 years. A further result is a high significance (r=-0.72) between the monthly precipitation for several stations in China and the Sea Surface Temperatures (SST) from 1911 to 1990. These results show the exceedingly close relationship of the Chinese precipitation situation to the Pacific climate.
